Penetration Testing in Chicago, IL
Chicago runs the world's derivatives markets and a disproportionate share of America's physical economy from the same few square miles: CME Group and Cboe Global Markets in the Loop, Northern Trust, the US headquarters of BMO and the Federal Reserve Bank of Chicago, Morningstar and the proprietary trading firms clustered around the exchanges, United Airlines at Willis Tower, the largest rail and intermodal hub in North America, and the academic medical centres of Northwestern Medicine, Rush, UChicago Medicine and Lurie Children's. The northern suburbs add Abbott and AbbVie in North Chicago, Walgreens in Deerfield, Motorola Solutions, Mondelez, Kraft Heinz, ADM and Conagra, and Argonne and Fermilab anchor a research corridor that stretches to Champaign. HackersHub runs offensive security engagements scoped to the threat model these organisations actually face: adversaries pre-positioning against market infrastructure, ransomware against hospital and dealer networks, business email compromise against treasury functions, and the Illinois BIPA, PIPA, CFTC, Regulation SCI, HIPAA, FFIEC and SOC 2 evidence that regulators, auditors and institutional customers now expect.
The Chicago and Illinois threat landscape
Chicago's attack surface divides along two lines: regulated market infrastructure and the clinical, biometric and consumer data that Illinois law protects more aggressively than any other state. The derivatives exchanges and clearing houses operate under the CFTC system safeguards rules, 17 CFR 38.1051 for designated contract markets and 39.18 for clearing organisations, which require vulnerability testing, external and internal penetration testing and controls testing on a risk-based cadence, with external penetration testing at least annually; the securities exchanges under Regulation SCI face an annual SCI review that includes penetration testing. Around them sit proprietary trading firms whose edge is latency and whose crown jewels are strategy code and market-data entitlements. Healthcare carries the clinical-ransomware exposure that has defined the US sector since 2020: the January 2024 intrusion at Lurie Children's Hospital took patient-facing systems offline for weeks and exposed records of around 791,000 people. The suburbs supplied the year's other landmark case when CDK Global in Hoffman Estates suffered back-to-back intrusions in June 2024 that forced roughly 15,000 North American car dealerships onto paper for the better part of two weeks, a reminder that a single Chicago-area software vendor can be the supply-chain path into an entire industry. Illinois regulates the result with unusual force. The Biometric Information Privacy Act (740 ILCS 14) requires informed written consent, a published retention schedule and a reasonable standard of care for fingerprints, face geometry and voiceprints, and grants a private right of action with liquidated damages of 1,000 dollars per negligent and 5,000 dollars per intentional or reckless violation; the August 2024 amendment (SB 2979) now counts one violation per person rather than per scan, which ended the nine- and ten-figure verdicts but left every timeclock, access-control reader and retail camera a litigation exposure. The Personal Information Protection Act (815 ILCS 530) requires notification of affected residents without unreasonable delay and of the Attorney General when more than 500 Illinois residents are affected, and the Insurance Data Security Law (215 ILCS 215), in force since 1 January 2024, obliges insurers and producers to run a written information security program built on a risk assessment and to test its key controls. Engagements in Chicago routinely uncover trading-adjacent and market-data networks reachable from the corporate domain, biometric templates stored far from the system that collected them, plant-floor OT in the suburbs reachable over vendor remote access, identity drift between hospital, university and physician-practice directories, and EDI and partner API access at logistics operators that nobody has reviewed since the contract was signed.

Industries we routinely engage in Chicago
Repeatable threat patterns by sector, drawn from engagement data rather than vendor marketing.
Exchanges, clearing houses & proprietary trading
Derivatives and options exchanges, clearing organisations, market-data vendors and the proprietary trading and market-making firms of the Loop and West Loop. External and internal penetration tests of trading, clearing and market-data environments, assumed-breach assessments of the corporate domain, and red team operations scoped against state-aligned pre-positioning. Evidence structured for CFTC system safeguards (17 CFR 38.1051 and 39.18), SEC Regulation SCI, NIST CSF 2.0 and SOC 2, with testing windows aligned to exchange maintenance periods.
Banking, custody & asset management
Custody banks and trust companies, the US operations of international banking groups, investment research and fund platforms, and the regional banks and credit unions of Cook and the collar counties. External and internal penetration tests, identity and privileged-access assessments, manual web-application and API pentests of digital-banking and client-reporting platforms, and BEC-resilience phishing simulation for treasury teams. Evidence mapped to the FFIEC IT Examination Handbook, the amended GLBA Safeguards Rule, OCC and Federal Reserve expectations and SOC 2. Our GLBA and FFIEC penetration testing guide at /insights/glba-ffiec-penetration-testing/ sets out what examiners look for.
Hospital systems & academic medicine
Academic medical centres of the Streeterville and Illinois Medical District campuses, multi-hospital systems across Chicagoland, children's and specialty hospitals, and the health-tech vendors serving them. HIPAA Security Rule evaluation evidence (45 CFR 164.308(a)(8)), clinical-network and medical-device segmentation review, identity-led methodology across hospital and university directories, and breach-readiness mapped to PIPA notification duties. Our HIPAA penetration testing guide at /insights/hipaa-penetration-testing/ covers scope and cadence.
Pharmaceutical, consumer & industrial headquarters
Pharmaceutical and medical-device campuses in North Chicago and Lake County, food and consumer-goods headquarters in the city and the northern suburbs, and the industrial manufacturers of the I-90 and I-55 corridors. Corporate-network and identity assessments, plant-floor and OT boundary testing under IEC 62443, laboratory and GxP system testing aligned to 21 CFR Part 11, and biometric timeclock and access-control reviews scoped to BIPA. SOC 2 and customer-driven evidence for the supply chains these headquarters sit on top of.
Transportation, logistics & aviation
Airlines and ground-handling operators at O'Hare and Midway, Class I railroads and intermodal terminals, freight brokers and third-party logistics providers across the region. External and internal pentests of operations and crew systems, partner EDI and API assessments, wireless and physical testing at yards and terminals, and reporting aligned to the TSA rail and aviation cybersecurity security directives and CISA cross-sector goals. Findings on operational systems are separated from enterprise-network findings so operations and IT can act in parallel.
Insurance, professional services & software vendors
Insurers and brokers of the northern suburbs, national law and accounting firms of the Loop, and the software and data vendors of the River North and Fulton Market tech cluster, including the dealer, payroll and HR platforms whose clients span every US state. Manual web-application and API pentests, cloud-configuration and identity reviews, and tenant-isolation testing for multi-tenant platforms. Evidence mapped to the Illinois Insurance Data Security Law (215 ILCS 215), SOC 2 Trust Services Criteria and PCI DSS v4.0.1 where payments are in scope. Our SOC 2 penetration testing guide at /insights/soc-2-penetration-testing/ sets out what auditors expect.
